This patch series converts mccmon6 to use Driver Model and Device
Tree in u-boot proper.
As the SPL is size constrained (and most notably the device has a strict
boot time requirements) for this board (and uses falcon boot)
- its conversion to DM/DTB will be added with separate patch series.
In the SPL/u-boot proper it now uses fitImage instead of legacy uImage and
DTB.
First patches are responsible for porting Linux's Common Clock Framework [CCF]
to u-boot. They add only support for reading clock frequencies and enabling
gate'd clocks.
Some notable changes:
- Use fitImage to boot Linux kernel (and also use of SPL's Falcon mode
when running from parallel NOR flash)
- DTS sync with kernel (tag: v4.20)
- Decoupling SPL and u-boot proper for easy SPL DM/DTS conversion
- Adding CONFIG_CLK for IMX6Q (reuse clock.c file functions)
- Conversion to DM_MMC, DM_SPI, and BLK (u-boot proper)
- Removal of DM_USB (as this board is not using it - no connector
present)
- Port of CCF (tag: 5.0-rc3) for imx6q ('dm tree', 'clk dump')
(more information regarding design decisions in the patch commit
message).
Footprint changes (u-boot.imx):
Before conversion: 345 KiB
DM conversion (without CCF): 415 KiB
With CCF: 421 KiB
